Side-by-side refrigerator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side-by-side refrigerators have complex structures and high part costs due to the use of turnover beams for sealing gaps between door bodies, which complicates assembly and increases labor costs.
Innovation Solution
A simplified door body locking assembly that uses elastic pieces and claws to lock and seal the gap between door bodies, eliminating the need for a turnover beam, thereby reducing part costs and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a turnover beam is used to seal the gap between door bodies, then the sealing reliability is improved, but the device complexity and part cost increase
Solution Approach 1:
The patent extracts and eliminates the turnover beam component from the door assembly, replacing it with a simplified sealing mechanism where the door seal directly engages with the counterbore structure on the opposite door body, removing the need for complex intermediate sealing components
Solution Approach 2:
The patent merges the sealing function and locking function into a single integrated mechanism where the door seal simultaneously provides sealing and engages with the counterbore to prevent door separation, eliminating the need for separate turnover beam components
2Reliability
If a turnover beam is used to seal the gap between door bodies, then the sealing reliability is improved, but the assembly time increases
Solution Approach 1:
The patent removes the turnover beam component and its associated assembly steps, allowing the door seal to directly engage with the counterbore structure, which significantly reduces the number of assembly operations required
Solution Approach 2:
The counterbore structure is pre-formed on the door body during manufacturing, allowing the door seal to be directly installed and engage with the counterbore in a single assembly step, eliminating the need for separate turnover beam installation procedures
3Reliability
If a turnover beam is used to seal the gap between door bodies, then the sealing reliability is improved, but the part cost increases
Solution Approach 1:
The patent eliminates the turnover beam component entirely, reducing the bill of materials and associated procurement costs while maintaining sealing functionality through the simplified door seal and counterbore engagement mechanism
Solution Approach 2:
The patent replaces the expensive, complex turnover beam with a simpler, more cost-effective door seal and counterbore structure that achieves the same sealing function at lower material and manufacturing cost
